LINT-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 417,613, dated December 17, 18853.

I Application filed October 22, 1888. Serial No. 288,823. (No model.)

To all whom, it may concern:

Be it known that I, JAMES WAYLAND, a citizen of the United States, residing at Newark, in the county of Essex and State of New J ers'ey, have invented certain new and useful Improvements in Lint-Machine's; and I do hereby declare the following to be a full, clear,'an d exact description ofthe invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of lintmachines in which the lint is formed by scraping the surface of a linen or cotton cloth, so that the fabric is partly disorganized or the texture is changed, so that a pile of loose fiber is raised from the warp and weft, and the cloth, while not entirely disintegrated, is

sufficiently so to allow of the newly-formed lint fabric being easily torn.

The object of the invention is to prevent or greatly lessen the noise which has been produced in operating the prior devices; to obtain a more perfect lint fabric and increase the output of the samewith a given expenditure of power; to reduce the cost of construction and limit the cost of repair; to secure a lighter machine, and one in which the wear can easily be taken up and the lintingknifecan be adjusted to obtain any desired depth of-lint.

The invention consists in the improved linting-machine and in the arrangements and combinations of parts substantially as will be hereinafter set forth, and finally embodied in the clauses of the claims.

V Referring tothe accompanying drawings, in which like letters and figures of reference indicate corresponding parts in each of the sev- -eral figures, Figure 1 is a side elevation of the improved machine. Fig. 2 is a side view of mechanism adapted to operate the feed-roll. Figs. 3 and at are views of an arm carriedby a rock-shaft and co-operating with an arm shown in Fig. 2 in supporting said feedroll, part of said roll being also shown. Fig. 5 is a plan of the machine. Fig. 6 is a section on line .2, showing the linting-tube and one of its bearings. Fig. 7 is a section of the same and the linting knife or blade, taken on line as, Fig. 5. Fig. 8 is asection of the tension device, taken on'line y, Fig. 5. Fig. 9 is a plan of a part of the tube and an end piece therefor for co-operating with the linting"- blade and said tube, and Fig. 10 is a view of a set-screw for holding said tube in'place.

I Fig. 1 1 is a broken side view, enlarged, and

more clearly showing the mechanism for feeding and linting the cloth; and Fig. 12 is an edge view or section showing more clearly the relation of the linting knife or blade to the co-operating parts.

In said drawings, a indicates a suitable bed or frame provided with a suitable roll or holder b for the unlinted cloth, a tension device c, by means of which the passage of the cloth to the linting mechanism is retarded, so that said cloth will be presented to said linting mechanism under considerable tension, feed mechanism by means of which the cloth is caused to travel toward the linting mechanism, and said linting mechanism. In part the said linting mechanism consists, preferably, of a tube d, adjustably held in end bearings e by set screws 6', which said end bearings are adj ustably held upon the frame a by set-screws e arranged in slot e in any suitable manner. The tubefmay be adjusted in its bearings by hand, it being turned pivotally in one direction or the other and afterward held rigidly by the set-screw, as will be understood upon reference to Figs. 6 and 9. The said tube d is longitudinally slotted,as at f, Figs. 9, 11, and 12, on the side toward the linting knife or blade, into which slot the edge of the said blade enters in the linting operation, as will be hereinafter described.

While I prefer a tube, inasmuch as it allows of a revolving adjustment, I may employ any other form in which two bearings d d form the slot f, back of which is an opening or chamber d through which or into which the loose lint may pass and be removed or prevented from accumulating to such a degree as to interfere with the linting operation by producing a cushion or bed. The said linting-knife g is arranged on a rock-framej, having suitable bearings j on the bed-frame, and allows of wear of the knife being taken up without interfering with theoperation of the machine. By loosening the set-screwl',

by which the knife is held onto the frame, the said knife maybe moved in or out by the hand to take up the wear or otherwise render the knife able to work more efficiently. The linting-knife g is secured on said framej on a seat Z, adjacent to the slot f in the tube, so that as the frame rocks to and fro the linting edge enters and is withdrawn from said slot, as indicated in Fig. 12. The knife 1 is caused to move toward said slot by suitable springs m, secured to projections or bearings n on the side of the rocking frame j opposite that on which the knife is seated, and to move in its opposite direction by a cam J, which engages an arm or bearing 1) of the rocking framej.

The cam v is arranged on a shaft q, Figs. 1, 5,and 11, and the latter is driven by a pulley r and has a fly-wheel s.

The fabric B to be linted travels between the linting knife or blade and the slotted tube, so that on the knife or blade entering the slot the cloth is forced out of its straight course and is brought into intimate contact with the three bearings, two on the tube and one 011 the knife. By causing the cloth to be pulled backward while in this position over the edge of the blade or knife I produce a very perfect pile of loose fiber or lint on the face of the cloth.

The mechanism I prefer to employ to draw the fabric over the knife when the latter is in the slot, as described, is illustrated more particularly in Figs. 1 and 11, in which if is a rock-shaft journaled in the frame a, which shaft at or near its center carries a projection u, which engages a cam 0 on the camshaft q. At the ends of the shaft t are ar-.

ranged feed-roll carriers or arms 20 10, between which is disposed a feed-roll 2, by means of which the cloth is fed forward to the linting mechanism. The reciprocating movement of the shaft 25 and arms 10 20' gives to the feed-roll a movement toward and from the linting-blade and tube. The reciprocal movement of the feed-roll on the shaft 15 is so timed that when the linting-blade is-withdrawn from the slot in the tube or between the bearings d d the feed-roll is moved downward or toward said blade, thus allowing the fabric to drop through or between the linting parts. Then the linting-blade makes a return movement and forces the fabric into the tube, as indicated in Fig. 12. The feed-roll is then forced or raised in a direction away from the linting-knife, so that the cloth is drawn over the edge of the blade, producing the pile of loose or partiallyloosened fiber desired. The surface of the feed-roll may be provided with any form of teeth commonly used in this class of machine adapted to prevent the cloth from slipping on the roll.

The spring 3, Figs. 1 and 5, gives to the feed-roll and its bearings a return motion after they have been acted on by the cam 11.

The cloth B is fed forward slowly by a mechanism arranged on the arm 10. This consists of a gear 4, arranged at the end of the feed-roll or feed-roll shaft 2, which engages a worm-shaft 5, having suitable bearings 6 (3 on said arm to and carrying a Wormwheel 7, which engages a ratcheted worm 8 on said arm. Said ratcheted worm engages a pawl 9, carried on the frame a near the shaft 25 and adjustable on said frame a, so as to vary the length of throw of the ratchetwheel, the supports 93 for the pawl being fixed to the frame by asuitable set-screw 94, passing through a slot 95 in the support,which set-screw, being loosened, allows said support to be moved toward or from the ratchet-Wheel, all as will be understood upon reference to Fig. 11. At each upward movement of the arm 10 the pawl causes the wheel 8 to make a partial revolution,and this motion is transmitted to the feed-wheel and cloth by the gearing just described.

The tension device 0, which I prefer to employ, consists of two parallel bars 0 0, held apart and connected at their opposite ends by end pieces 0 0 Fig. 5, which provide center bearings 0, arranged in the frame a. The said tension device is held in any fixed position by a set-nut 0 By turning the frame thus formed so that the cloth is given a very angular courseIsecure more or less tensionthe greater the angle produced the greater the tension, as will be understood. The cloth is held in proper relative position in the tension device by guides 0 which are held on the bars a c by set-screws c and move laterally thereon, so as to enable them to be brought into proper relation to the cloth to guide the same.

To increase the surface in engagement with the feed-roll, I have provided a bar 11, which runs parallel with said feed-roll, beneath which the cloth is caused to pass be fore engaging the feed-roll, as indicated in Fig. 1.

\Vhile I have thus specifically described the devices I employ in my operative machine, Ido not wish to limit myself to the exact construction shown.

I am aware that various changes and equivalent constructions may be employed without departing from the spirit of the invention.

In operating the device the cloth passes from the roll I) to and through the tension device to the feed-roll, where it is, while being slowly fed forward, given a reciprocating motion to and from the linting-blade. From the feed-roll the cloth passes between the lintingblade and the slotted tube, and from thence to the floor or to a suitable receptacle provided to receive it.

It will be observed that the blade in its movement does not strike any cushion or cooperating-bed, as in prior devices, and as a result I am enabled to secure more effective results Without the noise and jarring incident to such a construction and operation, and as a further result the wear on the machine is ICC his?

greatly reduced,'and the machine may therefore be run at a much quicker speed, and thus turn out a larger quantity of work in a given time.
